feat(options)!: disallow setting hidden options #28400

Browse Source 
Problem:
There are three different ways of marking an option as hidden, `enable_if
= false`, `hidden = true` and `immutable = true`. These also have different
behaviors. Options hidden with `enable_if = false` can't have their value
fetched using Vim script or the API, but options hidden with `hidden = true` or
`immutable = true` can. On the other hand, options with `hidden = true` do not
error when trying to set their value, but options with `immutable = true` do.

Solution:
Remove `enable_if = false`, remove the `hidden` property for options, and use
`immutable = true` to mark an option as hidden instead. Also make hidden option
variable pointers always point to the default value, which allows fetching the
value of every hidden option using Vim script and the API. This does also mean
that trying to set a hidden option will now give an error instead of just being
ignored.

Not all options are supported in all versions. This depends on the supported
features and sometimes on the system. A remark about this is in curly braces
below. When an option is not supported it may still be set without getting an
error, this is called a hidden option. You can't get the value of a hidden
option though, it is not stored.
